Service Procedure

Prototyping and Production Solutions for Automotive Industry

Rapid Prototyping for Automotive Innovation
Leveraging your design files and product specifications, we bring your automotive visions to life through prototyping. Our process involves crafting functional prototypes that closely resemble the final product in both form and function. This empowers you to meticulously assess and test the part, ensuring its alignment with your precise requirements. Our commitment to efficiency ensures a swift turnaround on prototypes, allowing you to move forward confidently in your automotive endeavors.

Swift and Cost-effective Adaptations
Efficiently adjust materials and designs
Detailed prototypes handle complex geometries

Design Validation and Testing (DVT)
YJC offers an array of materials and finishes aligning with your distinct design needs. This phase ensures functional and market-ready parts with both aesthetic finishes and end-use capabilities. Through diverse materials and surface options, we assess part performance, appearance, and functionality to validate their alignment with your unique design and product requirements. This phase, known as Design Verification Testing (DVT), ensures the part meets your exact specifications.

Durable Finishes and Superior Quality
Evaluating Appearance and Performance
Premium Parts for Market Testing

Production Validation and Testing (PVT)
PVT, the prelude to mass production, readies designs for full-scale manufacturing with cutting-edge quality control and production capabilities. Collaborating closely, we align with your production objectives, incorporating your feedback for final model adjustments. This stage also involves establishing the product supply chain, ensuring a seamless transition to high-volume manufacturing.

Validating Processes
Low-Volume Tooling
Functional Production Evaluation

Mass Production (MP)
Following successful product testing, we transition to mass production of end-use parts. Swift delivery and precise quality are paramount. Through advanced machinery, processes, and expert engineers, we achieve optimal quality, yield, cost efficiency, and lead times in automotive production.

Thorough Quality Inspection

Best Materials for Automotive Applications

Thermoplastics provide key benefits in the automotive industry, such as lightweight design, flexibility, chemical resistance, temperature resilience, strong mechanical properties, and recyclability. These attributes position them as a crucial material choice in automotive manufacturing.
Normal Thermoplastics: Polyethylene (PE), Polypropylene(PP), Polycarbonate (PC), ABS

Nylons is the ideal material choice for automotive sweating due to its excellent abrasion resistance, strength and stiffness, high chemical resistance, hygroscopic properties, excellent vibration damping characteristics, and manufacturing flexibility, especially in critical component applications requiring durability, strength, and chemical stability

Liquid Silicone Rubber
Liquid Silicone Rubber (LSR) is a go-to in the automotive sector. It seals, guards, and enhances diverse components like hoses, O-rings, and lighting fixtures. With temperature resilience, chemical resistance, and flexibility, LSR prevents leaks and delivers durability in demanding environments. The 2-Shot process merges parts seamlessly, reducing costs. In over-molding, LSR complements substrates like metal or plastic for efficiency and quality. LSR nails performance, reliability, and cost-effectiveness in automotive manufacturing.

With its strength-to-weight advantage, aluminum crafts lightweight parts – from engine blocks to wheels – enhancing performance and fuel efficiency. Combining strength, corrosion resistance, and more, it shapes engine components, body structures, brakes, and interiors.
Normal Aluminum: 6061-T6, 6063, 5052, 5083-H111, 2017, 7075-T651

Stainless Steel
Stainless steel brings robustness to automotive design. Its durability and corrosion resistance make it ideal for critical components such as exhaust systems, chassis parts, and fasteners.
